BURNER-DRUM-LIFTING MEANS.

Application led May 18, 1920. Serial No. 382,387.

The primary object of the present inven-y tion is tosimplify and improve the construction shown in this patent to render its operation more eflicient and the costof manne facture less expensive.

Specifically the objects of this invention are to provide an improved supporting bracket for mounting the burner head and burner drum lifting means;to provide an adjustable, extensible and contractible connection between the burner head and its lifting means; and to provide a simple burner drum elevating mechanism.

With these general objects in view the invention resides in the novel features of construc-tion, combination and arrangement of parts which will be hereinafter more particularly described and claimed and shown in the accompanying drawing in which:

Figure 1 represents a view partly in side elevation and partly in section of a burner,v

embodying my invention.

Figure 2 is a rear elevational view of the lower portion of the burner unit.

In the preferred embodiment of the' invention as shown in the said drawing, refer ence character 1 denotes a main supply pipe which, as is common in stoves 0f this character, extends horizontally from one end to the other` thereof, and is fed from a suitable constant level supply reservoir, and has a vertical upstan'ding supply pipe branch 2 for each burner head 3. In the present instance each burner head includes an annular trough 4 having an inlet into its bottom through which fuel is supplied from a supply stem 5, the latter being telescopically slidable in one of said supply pipe branches 2. Associated with this conventional structure is a burner drum 6, which drum can be seated upon the burner head or spaced therefrom as desired. j

The burner head 3 is raised and lowered by suitable means to be describedvwhich is.

carried by an improved bracket7, the same being formed from a plate having an intermediate attaching portion 8 engaged'with the supply pipe branch2 and extended ver. tically, a horizontal bracearm9 extending forwardly of the stove, and a rearwardly projecting horizontal guidek arm 10. From Figure 1 it will be seen that the arms 9, and 10 extend in opposite directions freni'l the upper and lower endsA ofy the attaching portion 8 and that said arm 9 adjacent this'connection with the intermediate.attachingportion is provided with a hole receivinggthe supply pipe branch 2. The bracket is secured upon said supply pipe branch 2v`by means of an encircling clip 11, vwhich clip and the vertical attaching portion 8 are clamped about said branch 2 by bolts and nuts 12.

The forward or free end of the arm 9 de pends downwardly as at 13, and is secured to a vertical brace plate 14 forming a portion of the stove frame, and has an operating shaft 15 journaled therein, saidl shaft being also journaled in the intermediate attaching portion 8. The outer end of the shaft 15 has a handle 16 secured thereto and also an indicating pointer 17 which is adapt-` ed to co-operate with a dial formed on the brace plate 14. The inner end of the shaft carries a crank 18 connected with the burner head 3 by the two parts 19 and 20 of an ex* tensible and contractible link.

The parts 19 and 20 form a pair of link arms, one being pivoted as at 21 to the inner wall 0f the burner head, whereas the other link arm 20 is pivoted to the crank 18. Onel of the link arms is slotted as at` 22 and the other has clamp bolts 23 extending through-V said slots to secure the two' parts together. By suc-h an arrangement the burner head' may be readily adjusted with respect to the 'crank 18, and thus aconsiderable range of movement of said head is possible by the rotation of the shaft 15.

The burner drum 6 is adapted to be moved, that is to say raised or lowered, independently ofthe burner head 3, and for this purpose a lifting rod 24 is extended through the burner head and slidably journaled in a plate 25 carried thereby. The upper end of this rod 24 has a head 26 engaging a portion of the drum 6 which is seated thereon as indicated in Figure 1, the lOW @I ld, 011 the Other hand, being slidably the burner drum 6 is in -normal position, the

`yoke 29 straddles the main supply pipe l and is seated thereon, as a result of which said supply pipe provides a support for said drum. On the other hand when the burner drum 6 is to he elevated for any purpose, for instance t0 light the burner head, the operator lifts upwardly on the handle 28 and after the yoke 29 is disengaged from the supply pipe l, the rod 2li is rotated slightly to disaline said y'oke and said main supply pipe l as ShoWnin dot and dash lines in Figure l. Thus when the handle 28 is released, the same is adapted to seat on the main supply pipe l and to support the burner drum in its elevated position.

l claim:

ln a burner structure, a burner head, a

supply pipe having a substantially horizontal and a vertical portion on which the head is supported, a burner drum normally seated on the burner head, a substantially vertical lifting rod connected With the drum, the lower end of the rod having an inverted U-shaped extension adapted to seat on said horizontal portion when thedrum is in its lowered position, and a handle on the outer end of said extension engageable with said said horizontal portion to support the drum when the latter is in its elevated posi tion.

ln testimony that l claim the foregoing l have hereunto Set my hand at Milwaukee in the county of Milwaukee and State of Wisconsin.

JOHN S. BRENNAN.
